| 摘 要： | 有关渤海湾盆地古近纪是否发生过海侵的问题争论了二十多年,至今尚无定论。尽管“海侵”论者提供了矿物学、岩石学、古生态学以及地球化学等多种标志,但是因为这些标志与标准海相标志比较,都有一定差别,而且至今没有发现确实可靠的海侵通道和明显的海相性递增现象,所以又出现了“海泛”论、“海啸”论和“陆相”论。几种观点长期并存,笔者认为要解决这一问题,可以从四方面入手①深入研究渤海湾盆地的构造背景,推断海侵通道存在的可能性;②进一步厘定已有的海相标志的准确性;③寻求新的、唯一的能区分海陆相成因的证据;④搜集国外在相关层位有类似沉积的地区,进行对比研究,并探索其成因。

| Abstract: | The question whether transgression happened in Paleogene of BohaiBayBasin has been discussed formore than 20 years, yet itwas not resolved. The scholars insisting on transgression p rovided manymarkers such asmineralogy,lithology, paleoecology and geochemistry, but these makers are not completely the same as normalmarine makers, moreover, the passageway and obviously increased makers of transgression have not been discovered, so "marine flooding" , " tsunami" and " terrestrial facies" appear, these viewpoints have coexisted for a long time. Penman considers that the question can be solved by 4 ways: ①The structural setting of BohaiBay Basin should be studied thoroughly to conclude possibility of the transgression's passageway. ②Reliability of marine makers provided should be newly considered. ③New and exclusive evidences are required. ④Similar sediment trap s in correlative strata abroad are collected to research contrastively |
